Synthetic Diamond Screeners

Synthetic diamond screeners separate natural diamonds from CVD and HPHT lab-grown stones, a job standard diamond testers cannot do. These instruments measure a colorless stone's transparency to shortwave UV light, sorting diamonds into types and returning a clear pass or refer result. A pass indicates a natural diamond, while a refer result flags a stone that needs further testing.

Our range includes portable handheld and desktop screeners from trusted brands such as Presidium, Gemlogis, GemTrue, and DRC, capable of testing loose stones and mounted jewelry, including small melee. Ideal for jewelers, gemologists, appraisers, and labs who need fast, reliable origin screening. All items ship worldwide from Bangkok, Thailand.
